Abstract
Abstract An arrangement for termination of a screened cable comprises: (a) a termination piece for the screen having a hollow, preferably metal, cable entry portion that can be positioned around the wire(s) of the cable, and (b) a dimensionally recoverable hollow article which can be positioned over at least part of the cable entry portion and the proximal part of the cable extending from the cable entry portion. The cable entry portion is provided with a gripping member, for example a thin annular ridge, for gripping the cable screen, placed around the entry portion. After the cable screen has been positioned over the cable entry portion and gripping member, the recoverable article is positioned over the cable and cable entry portion and is recovered to cause the gripping member to grip the cable screen.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
179 words
An arrangement for terminating the screen of a cable having one or more electrical wires and an electrical screen, which comprises: (a) a termination piece for the screen which has a hollow, electrically conductive, cable entry portion that can be positioned around the wire or wires of the cable, the cable entry portion having an outer surface that can be positioned inside part of the cable screen and the outer surface of the cable entry portion being provided with a gripping member for the cable screen, and (b) a dimensionally recoverable hollow article of a polymeric material which can be positioned over at least the cable entry portion and the proximal part of a cable extending therefrom, and which can be dimensionally recovered onto the cable entry portion and cable so as to retain the cable screen against the gripping member; the termination piece and the hollow article having an annular lip and a cooperating groove which can engage one another when the article is dimensionally recovered, so as to inhibit removal of the article from the termination piece.
Claim 2
Dependent Claim
179 words
An arrangement for terminating the screen of a cable having one or more electrical wires and an electrical screen, which comprises: (a) a termination piece for the screen which has a hollow, electrically conductive, cable entry portion that can be positioned around the wire or wires of the cable, the cable entry portion having an outer surface that can be positioned inside part of the cable screen and the outer surface of the cable entry portion being provided with a gripping member for the cable screen, and (b) a dimensionally recoverable hollow article of a polymeric material which can be positioned over at least the cable entry portion and the proximal part of a cable extending therefrom, and which can be dimensionally recovered onto the cable entry portion and cable so as to retain the cable screen against the gripping member; the termination piece and the hollow article having an annular lip and a cooperating groove which can engage one another when the article is dimensionally recovered, so as to inhibit removal of the article from the termination piece.
Claim 3
Dependent Claim
169 words
An arrangement which comprises: (a) an electrical cable having one or more electrical wires and an electrical screen, (b) a termination piece for the screen which has a hollow, electrically conductive cable entry portion into which the wire or wires of the cable extend, the cable entry portion having an outer surface over which part of the cable screen has been positioned, and the outer surface of the cable entry portion having a gripping member for the cable screen, and (c) a hollow polymeric article which is located over at least part of the cable entry portion and the proximal part of the cable and has been dimensionally recovered onto the cable entry portion and a cable so that the article retains the cable screen against the gripping member; the termination piece and the hollow article having an annular lip and a cooperating groove which engage one another as a result of dimensionally recovery of the article so as to inhibit removal of the article from the termination piece.
Claim 4
Dependent Claim
169 words
An arrangement which comprises: (a) an electrical cable having one or more electrical wires and an electrical screen, (b) a termination piece for the screen which has a hollow, electrically conductive cable entry portion into which the wire or wires of the cable extend, the cable entry portion having an outer surface over which part of the cable screen has been positioned, and the outer surface of the cable entry portion having a gripping member for the cable screen, and (c) a hollow polymeric article which is located over at least part of the cable entry portion and the proximal part of the cable and has been dimensionally recovered onto the cable entry portion and a cable so that the article retains the cable screen against the gripping member; the termination piece and the hollow article having an annular lip and a cooperating groove which engage one another as a result of dimensionally recovery of the article so as to inhibit removal of the article from the termination piece.
